  • Denture adhesive creams with improved extrudability
    Patent number: 4495314
    Abstract: A vehicle useful in a denture adhesive composition, and the denture adhesive composition containing such vehicle is disclosed. The vehicle comprises a gel consisting essentially of a mineral oil, a polyethylene wax and sorbitan monostearate in an amount of from about 0.25% to about 2.25% by weight of the gel. Preferably, the sorbitan monostearate is present in an amount of from about 0.5% to about 2.0% by weight. The gel may optionally contain up to about 10% by weight of polyisobutylene. The addition of sorbitan monostearate within the above amounts appears to lower the viscosity of the gels, and provides notable improvements in extrudability when the vehicle is employed in denture adhesive compositions.

  • Hot-melt adhesive and method
    Patent number: 4477636
    Abstract: A hot-melt adhesive comprising a self-curing unsaturated polyester resin having an air-drying functional group and an average polymerization degree of 8 or more has been found to have an excellent heat resistance and a high bonding strength when it is bonding-cured under heat and pressure. If an additive selected from a polymerization initiator, a polymerization promotor and a photosensitizer is incorporated into the present air-drying, self-curing polyester resin, the curing speed is extremely increased to such an extent as cannot be expected from the conventional curing type adhesives. The incorporation of such an additive into the self-curing unsaturated polyester resin is advantageously realized in the form of composite structures of various forms, e.g., a laminate form, a core-in-sheath form and an islands-in-sea form. Such a composite hot-melt adhesive structure is useful for improving a pot life.
